John Patrick's Video Poker: The Complete Guide to Playing and Winning

First he starts by telling you should play table blackjack instead, but if you are too timid to try to learn blackjack, you can minimize your losses by playing video poker his way. He doesn't seem to understand certain video poker games are positive expectation games (unlike blackjack, unless you can track the cards). His advice will quickly turn a positive expectation game (e.g., Duces Wild has a 100.7% expected payback if played flawlessly) into a negative one. One glaring example of his ignorance is "play the minimum for awhile until you see how he machine is paying". The fact is the greatest expected return is achieved by always playing max coins. He doesn't seem to understand each hand is a completely independent event from the prior hand. Some of the hands he says to "hold" are just wrong.

Parting shot: if the author is such as clever professional gambler why does he need to write books like this to make money?
